Specification of Letters Patent.

Patented Sept. 14, 1920.

Application filed October 19, 1917. Serial No. 197,514.

To all whom it may concern:

Be it known that I, FRED S. WARE, a citizen of the United States, residing at Fulton, in the county of Oswego and State of New York, have invented a new and useful Fuel- Saving and Speed-Increasing Attachment for Engines, of which the following is a specification.

The present invention relates to an attachment for internal combustion engines, and is designed for introducing, at the will of the operator, an auxiliary supply of heated air into the intake manifold of the engine, whereby to effect a saving in fuel and obtain greater speed andpower.

It is the object of the invention to provide a novel and improved device of that character which can be readily installed upon an engine, and which will serve its office in a thoroughly eflicient manner.

\Vith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of the attachment as applied to an engine.

Fig. 2 is a plan view thereof.

In carrying-out the invention, an elongated tubular air heating chamber 1 is disposed longitudinally upon the exhaust manifold 2 of the engine, and is fastened thereon in any suitable manner, such as by means of wire bands 3 or their equivalents embracing said chamber and manifold. The rear end of the chamber is open to receive air, and said chamber being in contact with the exhaust manifold will be heated thereby, in order to heat the air flowing therethrough.

An elbow 4 attached to the forward end of the chamber 1 extends to one side and is connected to a controlling valve 5 extending at right angles from the forward end of the chamber, and a second elbow 6 is attached to the valve 5 opposite to the elbow 4. A pipe 7 isaconnected to the elbow 6 and extends in an inclined position downwardly and rearwardly, the lower end portion 8 of said pipe extending at right angles toward the vertical plane of the chamber 1 below the horizontal planethereof. This end portion 8 of the pipe 7 is 'threadedly or otherwise attached to the intake manifold 9 of the engine, so that when the valve 5 is open, the heated air will be drawn into the intake manifold to mix with the carbureted air flowing from the carburetor.

An upstanding priming valve 10 can be attached on the end portion 8 of the pipe, said valve being provided with an upper priming fuel cup 11 in which a small quantity of fuel can be poured to pass-into the pipe 7 when the valve 10 is open, in primin the engine.

11 order that the valve 5 can be readily controlled by the operator, an inclined rod 12 extends rearwardly in an inclined position through the dash 13 of the automobile, and is provided at its rear end with a handle 14 to be turned by the operator. The fort ward lower end of the rod 12 has an eye or loop 15 loosely engaging the handle 16 of the stem 17 of the valve 5, providing a flexible connection between said rod and valve stem, and enabling the valve to be readily turned to control the flow of air through the chamber 1 and pipe 7 into the manifold 9.

It has been proven by actual test, that a saving in fuel is accomplished, as well as obtaining greater speed and power. Thus,

in making tests, on an even road, the spark and throttle control have been set so that the automobile travels at a uniform speed of. fifteen miles per hour, with the valve 5 closed. Then, by opening said valve, the speed of the automobile immediately increases to an appreciable extent, usually to twenty miles an hour. It will be noted that the chamber 1 is of appreciably larger diameter than the pipe 7', whereby the flow of air through the pipe 7 is restricted, while the flow of air in the chamber 1 will be of much less velocity, thus assuring the heating of the air in the chamber 1 before passfold of an internal combustion engine, of a relatively large air heating drum secured upon. and extending along the exhaust manifold in close proximity thereto and having one end open directly to the atmosphere, there being a continuous unobstructed opening extending through the drum from one end to the other thereof, a relatively small pipe connected to the intake manifold and to that end of the drum remote from the end open to the atmosphere, a Valve in said small pipe near its junction with the heat ing drum, means for operating said valve from a point remote therefrom, and a priming valve in said small pipe and adjacent the intake manifold, the connection between the relatively small pipe and the heating drum being stepped.

In testimony that I claim the foregoing 15 as my own, I have hereto afiixed my signature in the presence of two Witnesses.

FRED S. WARE.
